Be it known that I, PHILIP RIEDELE, a, citizen, ot' the "United States, residing Angeles, in the county of'Los7An-- geles and State of California; have invented a nevi` and useful Automobile Bumper, oi

' -which the following 'is a` specification.

This invention relates to automobile bumpers of the resilient bar type, that is the type of bumpers having resilient, bars of greater height than width and positioned so that the bars are adaptedto flex more, readily ina horizontal than in a vertical direction, land the invention refersfparti ularly to the resilient bar type of bumper in which a plurnlit v of vertice y alined bars are employed to provide zillbroadened impact front.

This invention has tor an olijectv gielcon#E struction of a bumper which Will'onplise.y a multiple front impact /structure-so rein? forced and carried by a secondary impact structure positioned to the rear of the front structure, that improved impact absorbing' properties are provided in the bumper and the forward impact barsare carried in a simple and effective manner. A

More specifically. an object of this invention lis to provide a duplex bumper front having free and flexible ends. with the corresponding ends held spaced apart and held rigidly together but adapted to Afreely flex, and to provide such a duplex bumper front vwith a supporting and reinforced impact bar 'oined to the front structure at three equsily spaced apart points located between the. .freely flexing ends of the/bumper.

Otherobiects and advantages of this in-l vention will be readily apparent from the description of the preferred embodiment of the invention.' 'In theV accompanying drawings, l have illustrated one example of the invention in which Figure 1 is a fear elevation, Figure is a plan view of Fig. 1, l Figure 3 is a front elevation of the bumper,

Figure 4 is a section on the line 4 4 of Fig. 3, and v Figure 5 is a fragmentaryview partially in longitudinal horizontal section of the central construction of the bumper. i

Referring to the drawings, the bumper comprises two complementary bars 1, which are formed of a resilient material and are plates 15 abut-tip AUTOMOBILE BUMPER; Y

2,` terminatingin e'yes 3.' The complementary bars 1 are arranged horizontal in the .bumperfstructure`parallel one tothe other. s aced apart vertically and vertically alined, he corresponding eyes 3 of the comple, mentar bars 1 are joined by bolts or pins 4, whic f carry spacers 5 between the bars 1Q `The ends 2 are thus rigidly connected together and strengthened so that they'areA less easily damaged.

The frontstructure of the bumper is oarL rled by a resilient barv 6 disposed mainly (lll ' to the rear of 'the bars .1 and extending in substantially the same direction as the front bars 1sa'id bar 6 thus roviding a, second ary irripact'member. T e bar 6 1s provided with a. Veshaped bend 7 at its medial.isolo-- tion which. positions the bottoml 8 o the bend'close to the middle of the front bumper-;Vv

structure. 9 indicates a form 'of clamp for4 v E;

clamping the part 8 of the bar 6 to the front barsA 1. said clamp comprising a plate 1 0, disposed in front and pressed against the `upper and klower bars 1. and a second plate 11 disposed behind the bars 1 and 'Y engaging the uip'per and lower bar,the1part 8 ,B5

'plates 14') .and 11 being held togethervby a bolt 12. extending therethrough. YThe opposed ends 13 of the bar 6 are bent forward to position the extremities .close to the front hars 1 and such bends inthe bars 6 preferably do not loop around 180"i vor provide inturncd ends, but ositi'on theends 13. turned outward from t e remainder of the hars 6. The bar 6 is constructed of shorter length than the front bars 1, so that thtl ends 13 are disposed a considerable distance from the eyes 3 of the fron-t bars 1. Thel ends 13 are held by clamps 14 to the front bars .1. The clamps 14 com rise the front sides o the bars 1 and having ooked ends 16 extending over the .top and bottom of the front structure; 17 indicates secondary plates abut,-A

loo

ting at their forward faces the rear faces of the hars 1 and abutting at their rear faces the ends 13 of the bar 6. The plates 15 and 17 and the ends 13 are bolted together by bolts 18.

By this construction. it is seenthatvthe bumper is provided with a duplex bumper front which foriisfwith the secondary impact bar 6 two resilient closed sections, while still providing free ends 2. The connection 4between' the endsl 13 and front bars 1 does not, absolutely hook the ends inl fixed posiy tion, as iii-the type o'f bumper wher@ `the secondary impact member 'is y bolted to the extremities of the 1 ront structure' l, but upon a severe impact applied to the' front structure the clamp 1% may slide' `slightly 'along the front bars 1 towards the yeyes `3. and this action will assist in o-vei` coming and absorbing such impacts. Io obl tain the full advantage of this action the ends 13 shouldbe out turned, as shown.-
